Description

Description

Currently when a MouseWheel event is triggered, the TouchPhase is set to Moved. For the Touchpad the phases Started, Moved and Ended are used.
It is confusing when a wheel event with a phase of Moved is send without the Start.

Qt is using NoScrollPhase for mouse wheel events and for the Touchpad start, update and end (https://doc.qt.io/qt-6/qt.html#ScrollPhase-enum)

Research direction

Start by tracing how MouseWheel events assign TouchPhase and where touchpad phases are represented in the event API. Compare the requested behavior with Qt's NoScrollPhase distinction, then define the event semantics and verify that mouse-wheel and touchpad sequences can be distinguished consistently.
